    Here is the build so far:
    Z7 Crossover
    Z7 Downpipe with v-band
    Precision Turbo 6262
    Manual Boost Controller
    MVS Wastegate
    Z7 A2A IC w/ 50mm BOV
    Braided Fuel Lines
    65lb Injectors
    L26 UIM & LIM
    ZZP 304 Stainless Front Powerlog
    ZZP 304 Stainless rear Turbo Powerlog

    heres a few pictures:







    Im looking for some digrams that ive recently seen of the way they routed all the vacuum tubing to everything. Anybody have a link to that thread that knows what im talking about? Im going to be running an AEM boost gauge with that, where would that tee into as well?
    It was mentioned to me to make sure im not boosting the crankcase, exactly how do i know if i am or not?

    Vacuums go as so:

    BOV- any vacuum behind the TB/ vent to atmosphere?
    Wastegate- vacuum on turbo housing
    Boost Gauge- anywhere on the IC piping

    "boosting the crankcase" is dealt with through valve cover breathers/ pcv breathers.

    idk if im missing something, im tired.

    correct

    Wastegate- vacuum on turbo housing
    wrong, goes on the engine vacuum.

    Boost Gauge- anywhere on the IC piping
    Wrong again, engine vacuum

    "boosting the crankcase" is dealt with through valve cover breathers/ pcv breathers.
    Wrong again, on L36/L67 motors, there is a fresh air draw in the throttle body that has to be blocked, on L26 intakes, the fresh air draw is on the top of the intake, and can be capped or left open.

    You gonna put a blanket on that snail to help keep temps under the hood down ? Also as close as your radiator line is going to be to that turbo and exhaust it may not hurt to go braided on the rad lines because i could see that wearing or melting the rubber of the hose. Just my $0.02.

    PS Your setup looks very nice! I wish I would have went this route from the beginning.

    very nice upgrades compared to my Z7 kit. zzp did great with the v bands. you should have wrapped up the downpipe with heat wrap. as for the turbo blanket i bought mine from ptpturboblankets. i put a spark plug bootie over the coolant temp sensor because its so close to the crossover.

    I do plan to buy a turbo blanket for it. The upper radiator hose will be fine, I'm more so worried about the coolant temp sensor like mention above and the tranny harness under the turbo.

    It was mentioned to me by matt to not wrap the downpipe and crossover due to possible cracking.

    Thanks for the complements on the setup.

    Badass setup you've got going there so far man. I'm looking into going turbo instead of swapping an l67. Lookin forward to the end result and hearing your feedback.

    nipple on the turbo housing isnt engine vacuum..? IC piping isnt vacuum?
    My SRT4 has been running the vacs like that for years and everything works fine.

    put the spark plug booty on the coolant sensor. the turbo blanket will protect the trans harness because it wraps around the whole side of the turbo. why would stainless steel crack? my downpipe is wrapped up nice. too much heat especially near the master and the throttle body

    No, and the turbo housing is a lousy place to get boost reference from in my experience.

    any turbo car ive ever worked on has the wastegate vacuum connect to that nipple. What do you mean by "lousy"?

    it sucks? I get turbulence?

    I tried it on my HX35 and it would not make less than 17psi, I moved it to the motor side and it made 13. In theory, it should make less boost sourced at the turbo, but something else decided against that.

    Simply put, nobody in the 3800 turbo world puts their wg reference there. I run my nitrous switch on that port, but thats it.

    hahaha. Tha "Box". Shoot me a PM man. Im off tomorrow so we could meet up and ill let u check it out.

    To all the comments, Thank you. Finally took the leap. Wish i woulda done this quite awhile ago.

    Went ahead and wrapped all the pipes with header wrap and put a spark plug boot on the coolant temp sensor. Gonna be ordering my turbo timer and turbo blanket later on this week. And will be building a vac block throughout this week as well. more pics coming soon.
